Good day..... I,m afraid I have not had much luck in locating him, I think the parish church for Yaxtley is St, Mary.
The only thing that I can think of at the moment is that maybe he was illegitimate therefore not born a Nunn, if so mother may have married fairly soon afterward as they often did to a Nunn and subsequently took his name .
This is pure speculation but its a scenario I have come across many times also he may not have been, his father may have died whilst he was very young, mother remarries and again he takes the name, never knowing otherwise
